1 Claim. (Cl. l2056.5)

The present invention relates to window constructions and especially toa novel sealing means for a double glazed assembly in which the pane ofglass are mounted and maintained inv spaced relation.

Among the objects of the present invention is the provision of a novelseal cooperating with each pane of glass in a manner to most eectivelyseal the space between the panes. In the preferred embodiment, eachsealing element or packing member is of substantially wedge-shape andmounted in a substantially V-shaped groove or recess provided in thesash rail with the base of the sealing element or packing engaging theinner face of the glass adjacent an edge thereof. In addition to sealingthe space between the panes, the sealing' elements are so disposed as toretain the glass with a resilient gripping pressure to therebyeiectively retain the glass and eliminate danger of breakage of thepanes when the glass is subjected to stresses or strains.

Further objects are to provide a construction of maximum simplicity,eiciency, economy and ease of assembly and operation, and such furtherobjects, advantages and capabilities as will later. more fully appearand are inherently possessed thereby.

'I'he invention further resides /in the construction, combination andarrangement of parts illustrated in the accompanying drawing, and while-there is shown therein a preferred embodiment, it is to be understoodthat the same is susceptible of modification and change, and oomprehendsother details, arrangements of parts, features and constructions withoutdeparting from the spirit of the invention.

In the drawing: v

Figure 1 is a view in front elevation of the novel window sash with aportion broken away to more clearly disclose the interior construction.Figure 2 is an enlarged fragmentary view in vertical cross section takenin a plane represented by the line 2-2 of Figure 1.

4Figure 3 is a View similar to Figure2 but disclosing an alternate.construction of sealing means.

Referring more particularly to the illustrative embodiment shown inFigures 1 and 2 of the drawing, the window sash I comprises a side orsash rail 2 having a reduced inwardly extending portio' 3 provided withoppositely opening substantially V-shaped grooves or recesses 4 and 5.Positioned within each recess or groove is a substantially wedge-shapedsealing element or packing 6 formed of a resilient material such asnatural or synthetic rubber. Against the base or projecting sealingsurface of each sealing element is mounted a pane of glass 'I and thispane is retained by means of a clamping strip or molding 8, the latterbeing secured to the side rail 2 by suitable means such as flat-head orcountersunk machine screws or other suitable securing means 9.

In order to permit suitable drainage from the exterior and interior ofthe Window sash, the abutting face I0 of the clamping strip or molding 8is slotted at II and the sash rail 2 is slotted at I2 and I3 throughouttheir length to permit proper drainage to the exterior of the sashsetting of any condensate collected within and between the sash rail andits moldings.

In order to provide a most elective seal between the sash rail and thespaced panes of glass l, the sealing elements 6 when not compressed havetheir sides I4 disposed at an angler of approximately 45 and with theside Walls of the recess ydisposed at an angle of approximately topermit the sealing element to be readily compressed When pressure isapplied through tightening of the machine screws 9. 'I'his angularrelationship is more clearly shown in dotted outline in Figure 2. Thusas the machine screws are tightened and themolding is moved inwardlyinto contact with the sealing element or packing, the rounded base orsealing surface of the latter is compressed, suiiicient space being leftat each side of the sealing element and between it and the side wallso-f the recess, to allow for pivoting action of the sealing elementduring and even after it has been compressed into its normal operatingposition. In order to prevent the corners I5 of the seal from beingextruded and pinched between the adjacent angular surfaces of the siderail and the adjacent surfaces of the glass, these corners I5 are shownas rounded. The vertex I6 of the sealing elements is also rounded sothat it may pivot within the rounded orv curved base of the recesses 4and 5 and maintain the sealing eiect should the glass be subjected tolongitudinal movement.

FigureS discloses an alternate construction in which the side rail I1 isformed with oppositely opening substantially channel-shaped recesses I8adapted to receive a sealing element I9 of circular cross section. Thediameter or cross section of each sealing element is less than the widthof the recesses or grooves I8 so as to ,permit the sealing element to beplaced under compression when the clamping strip 8 is applied. In otherrespects this construction issimilar to that shown in Figures 1 and 2and similar reference characters have been applied to the correspondingparts.

The sash rail and clamping or molding strips in either form of theinvention are preferably of metal, although they may be formed of Woodor 1 other material suitable for the purpose.

Having thus disclosed my invention, I claim:

A window sasl'lgco nstructiogn` v,formounting a pair of fwindow'paneswin spaced relation; comprising a sash railhaving a ledge at eachside ypart adapted to engage .the exterior face of a pane thereof forsupporting a pane and a reduced pro- .Y V,

jection having a substantially V-shaped recess' irl` each side of theprojection and opening-out-v Wardly therefrom, a substantiallywedge-shaped resilient sealing ring composed Jlfqrubherflikematerial ineach recess, said ring 'prio to sealing deformation being Wedge shapedandhaving the and force the interior face ofthe pane into sealingcontact With the base of a sealing element to deform the rounded baseinto substantially fiat sealingzcontact with the pane but leaving spacesbetween the side Walls of the recess and the sides ofthe ring;
